Abstract

SE PRESENTA UN PAR DE ELEMENTOS DE REFINADO COOPERANTES (10, 11) DISEÑADOS PARA UNA REFINADORA DE DISCO PARA DESINTEGRAR Y REFINAR MATERIAL LIGNOCELULOSICO EN UN HUECO DE REFINADO ENTRE DOS DISCOS DE REFINADO OPUESTOS QUE GIRAN UNO CON RELACION AL OTRO. LOS ELEMENTOS DE REFINADO (10, 11) ESTAN DISEÑADOS PARA SER COLOCADOS DIRECTAMENTE EN LA PARTE FRONTAL DE UNO Y OTRO DISCO DE REFINADO, OPUESTOS. CADA UNO DE LOS ELEMENTOS DE REFINADO ESTA FORMADO CON VARILLAS (12) Y RANURAS INTERMEDIAS (13), QUE EN LA PARTE EXTERIOR (16) DE LOS ELEMENTOS DE REFINADO (10, 11) SE DISPONEN EN UN NUMERO DE ZONAS LIMITADAS (17-24) SITUADAS RADIALMENTE FUERA DE UNO Y OTRO DISCO. CADA ELEMENTO DE REFINADO COMPRENDE AL MENOS UNA ZONA ((18, 20 Y, RESPECTIVAMENTE, (21, 23)) EN LA QUE SE COLOCAN LAS VARILLAS (12) DE FORMA MAS DENSA QUE EN LA ZONA COLINDANTE (17, 19 Y, RESPECTIVAMENTE 22, 24). ESTAS ZONAS MAS DENSAMENTE CONFORMADAS (18, 20) EN UN ELEMENTO DE REFINADO (10) ESTARAN RADIALMENTE DESALINEADAS SIN SUPERPONERSE EN RELACION CON LAS ZONAS MAS DENSAMENTE POBLADAS (21, 23) SOBRE EL OTRO ELEMENTO DE REFINADO.A PAIR OF COOPERATING REFINING ELEMENTS (10, 11) DESIGNED FOR A DISC REFINER TO DISINTEGRATE AND REFINE LIGNOCELLULOSIC MATERIAL IN A REFINING HOLE BETWEEN TWO OPPOSITE REFINING DISCS WHICH ROTATE ONE IN RELATION TO THE OTHER, IS PRESENT. THE REFINING ELEMENTS (10, 11) ARE DESIGNED TO BE PLACED DIRECTLY ON THE FRONT OF ONE AND ANOTHER REFINING DISC, OPPOSITE. EACH OF THE REFINING ELEMENTS IS FORMED WITH RODS (12) AND INTERMEDIATE SLOTS (13), WHICH ON THE EXTERNAL PART (16) OF THE REFINING ELEMENTS (10, 11) ARE DISPOSED IN A NUMBER OF LIMITED ZONES (17- 24) LOCATED RADIOALLY OUTSIDE ONE AND ANOTHER DISC. EACH ELEMENT OF REFINING INCLUDES AT LEAST ONE AREA ((18, 20 AND, RESPECTIVELY, (21, 23)) IN WHICH THE RODS (12) ARE PLACED MORE DENSICALLY THAN IN THE SURROUNDING AREA (17, 19 AND, RESPECTIVELY 22, 24) THESE MOST DENSELY CONFORMED ZONES (18, 20) IN A REFINING ELEMENT (10) WILL BE RADIOALLY MISALIGNED WITHOUT OVERLAPPING IN RELATION TO THE MOST DEENSILY POPULATED ZONES (21, 23) OVER THE OTHER REFINING ELEMENT.
